I think it says something along the lines of, "The information adds to the development of the scenario, but if you try looking ahead from time to time that is okay.", but I'm not completely sure. Could someone explain the use of 応じる?

I'm not sure exactly what they're talking about without context, but I would at least translate it as something closer to "Information will be added based on the progress of the scenario, so it might be good to take a look from time to time."
